Layer Details
Knitted cover
A knitted cover tops the mattress, adding a final soft layer against you.
Microquilted layer
A micro-quilted finish gives the surface a smooth, soft feel from the first night.
Soft White Fibres
Soft synthetic fillings sit near the top to create a cosy feel. This is where much of the plushness comes from.
Memory Foam
Memory foam cradles your shape for a cushioned feel, which means pressure is spread rather than concentrated. It's made with graphite to help disperse body heat.
Mini Pocket Springs
Small, individually cased springs add a responsive comfort layer with soothing pressure relief.
Pocket Springs
The main support layer: springs encased in individual cloth pockets that adapt to movement, distributing support to each part of your body.

Key benefits
- Space to sprawl on your own: The UK small double is 30cm wider than the UK single, so you can roll and shift on the cushioned surface without meeting the edge.
- Fits a tighter double room: At 15cm narrower than the UK double, it leaves a little more floor in a box room or loft conversion, which can decide whether a wardrobe door still opens.
- Cushioning for solo side sleepers: Graphite memory foam over two layers of pocket springs means a lone side sleeper gets give at the hips and shoulders across the whole 4ft x 6ft 3in surface.
- Sensible for the guest room: The pocket springs adapt to movement and support each part of the body individually, which suits visiting couples who share it for a weekend.
- Frames are easy to find: A 4ft frame is a standard UK size, although the 36cm depth means buying small double deep-fitted sheets rather than standard ones.
This size suits you if...
You sleep alone and want a soft, roomy bed, you're a teenager who has outgrown a single in a room that can't spare much floor, your bedroom is a loft conversion or compact flat where a UK double would crowd the space, or couples only share it for occasional stays.
Consider another size if...
You share the bed every night, or you're tall and 190cm feels short. We'd recommend the UK king instead, and we suggest at least 2.7m x 2.9m for it.

FAQ's
Is the Sleepeezee Memory Ultimate 9500 small double big enough for one adult?
For most solo sleepers, yes. At 120 x 190cm it's 30cm wider than the UK single, which gives you real room to spread out on a soft, sink-in surface. If you're tall, bear in mind the length matches the UK single and UK double, and only the UK king and UK super king add length.
Will the Memory Ultimate 9500 in a UK small double fit a small bedroom?
We suggest a room of at least 2.4m x 2.8m. The mattress itself is 4ft x 6ft 3in, so it can suit a box room, a small second bedroom in a rental or a room you've downsized into. Measure door swing and any sloping ceiling before you order, as the mattress is 36cm deep.
Can a couple share the Memory Ultimate 9500 small double every night?
It works for the odd night, which makes it a good fit for a guest room. For nightly sharing, the UK double is a slightly roomier choice, giving 67.5cm each for two people. We suggest at least 2.6m x 2.8m for the UK double.
What sheets fit a Sleepeezee Memory Ultimate 9500 small double?
Look for small double (4ft) fitted sheets with a deep pocket. This mattress is 36cm deep, so standard fitted sheets may slip off the corners. A standard double duvet suits the UK small double width.
Should I buy the Memory Ultimate 9500 in a small double or a double?
The UK small double is 15cm narrower than the UK double and the same length. Choose the UK small double if you sleep alone or your room is tight. The UK double suits a couple sharing nightly, and we suggest at least 2.6m x 2.8m for the UK double.
